as you see i don't have a vga cable or anything to connect so will it be possible to connect another monitor to my computer. Also does my computer have hidden ports, if you look at the picture above, and look at the right side, you will see a picture of a lock and then a little opening what is that and how can i get that open? is that extra ports behind that?

You can also use your service tag#, enter it and follow the website for what you need for other items. Isn't this PC an AIO type, isn't your display not working. If so AND WHAT IS FOUND ON MANUAL @WEBSITE, you need to replace the video card in order to get it to work or if you find no ext. video port, that option was part of yet another video setup. basically, does yours have any at all?

my computer only has a ac adapter on the port on the back, a few usb ports, Ethernet cable and that is it. no vga or anything like that to be able to add another monitor now where can i add my service tag? look in the first post on that picture that is what my computer has in the back

sorry for the bump, but can anyone tell me what the picture of the lock on the back on the computer is? and has that little opening? how can i open that? and is there like extra ports behind it? pic is below

well i called dell and they told me to buy a vga video card they told me that is the only way so i can connect another monitor. so i got one and my computer DOES detect the vga connect/other monitor i have set it to extend both displays however on my second moinitor it is still showing a black screen. again my computer detects the monitor but it is still showing black on the monitor im trying to connect any help
